Protein

Lactosylceramide alpha-2,3-sialyltransferase

Gene

St3gal5

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli

Functioni

Catalyzes the formation of ganglioside GM3 (alpha-N-acetylneuraminyl-2,3-beta-D-galactosyl-1, 4-beta-D-glucosylceramide).By similarity

Catalytic activityi

CMP-N-acetylneuraminate + beta-D-galactosyl-(1->4)-beta-D-glucosyl-(1<->1)-ceramide = CMP + alpha-N-acetylneuraminyl-(2->3)-beta-D-galactosyl-(1->4)-beta-D-glucosyl-(1<->1)-ceramide.
